Phase synchronizing nodes in a telecommunications network

摘要

For phase synchronizing nodes, on a node by node basis, following a tree-structured phase distribution network using the infrastructure of a telecommunications network, a first node transfers to a second node phase information substantially in phase with a phase reference internal to the first node and position signaling of the phase information with respect to component elements, such as bits, of a data signal carried by a link linking the nodes. The position signaling can be the number of component elements separating it from the phase information in a packet. The time to transfer the phase information through the link is precisely compensated.

1. A method of phase synchronizing nodes linked by links of a telecommunications network, including:
transferring from a first node to a second node phase information substantially in phase with a phase reference internal to said first node and a position signaling information which signals the position of said phase information with respect to component elements of a digital data signal carried from the first node to the second node by a link of the network linking said first node to said second node wherein said second node is to be synchronized with said first node, wherein said position signaling information precedes said phase information in said digital data signal.
